How to make AC work with your swap, aka: Need help with AC wiring thread Options

[lagos]

ok... so my AC hasnt worked since the swap and i figure now is a good time to wire that crap up. so i have my harness apart and im trying to look at the wiring diagrams to figure out a few things. seems like i need some help.

"ac amplifier" in the diagrams means the main AC compressor, correct?

on it, is a plug called A8 (looking at the 5sfe diagrams). the harness goes from there to a plug called IM1 and then 3 wires go to the ECU's 1st plug. where is IM1 located ? is it the white, 5 wire plug that goes from the 3s hanress, and plugs in right behind the glove box?

I'm also curious as to why there was any rewiring of the A/C system?

For my swap, I left all my A/C wiring stock (along with keeping the stock compressor). At that point, all you need to wire up are the couple wires that go to/from the ECU related to A/C idle up and A/C cut...

Without even hooking those wires up, I get A/C - just no idle up (I only use it on the freeway at the moment) and no A/C cut (turn it off before full throttle).

I looked into swapping over to all ST205 stuff, but putting together that mish-mash of parts and wiring looked like it was going to be hell.

do you have an st205 swap? if you do, then all your AC stuff probably just plugs in without having to rewire anything.

for the st185, you have to rewire a few things. its about 5-6 wires total that you need to rewire to make it work. its pretty easy.

Yup, ST205 - but into a '90 Camry... So no, nothing plugs in between the two A/C systems.

My clip had auto A/C and RHD, so some of the stuff probably would have been different anyway.

I left everything A/C related except the two wires to the ECU original. My only issue is that the ST205 ECU has 3 wires to the A/C system, and none of the pin names match up...

Either way though - it sounds like you have a decent plan of attack for your A/C system.
